10m FT8 RX

At 0720z I turned on the FT817ND and indoor loop on to 10m FT8 RX. In the last few days my results have been disappointing. I suspect the loop is quite a bit less efficient than a dipole.

UPDATE 0847z:  G0FWX (160km) spotted. As he was quite strong, I wonder if this was aircraft scatter

UPDATE 1330z: 4 stations spotted with some Es in the form of IK7LJZ (1664km).  After comparing my RX results with G0LRD who is using just a low dipole on 10m, I think my loop must be at least 6dB down.

    Hi Roger,
    It's probably worth noting that 6m high for a 10m dipole is the lowest 'optimum height' in terms of gain (about 7.7 dBi) and take-off angle (about 22 degrees). That's one of the nice things about 10m - getting a decent height in terms of wavelength isn't so difficult.
